Ursula is the main antagonist of Disney's 1989 animated feature film The Little Mermaid. She is a villainous cecaelian sea witch who "helps" unfortunate merfolk to achieve her own goals. She ultimately seeks to dethrone her longstanding rival, King Triton, so that she may rule the undersea city of Atlantica, and all the ocean.

Ursula's fervent confidence, flamboyance and theatrics have made her one of the most popular and iconic of all the Disney villains, and she quickly became one of the franchise's primary members following her debut.

Ursula is based on the "sea witch" character in Hans Christian Andersen's story "The Little Mermaid". In the original story, the sea witch is a neutral enabler, but for Disney's animated adaptation, the character was modified into a full-fledged antagonist and plays a larger role in the overall story.

During pre-production, Ursula was not originally designed as a Cecaelia; a legendary hybrid of human and octopus. It was thought that she would be another species of sea creatures, such as a rockfish or lion fish, or would have a snake-like appearance, as revealed in The Disney Sketchbook. The production team then saw a documentary about octopi and decided that their multiple arms and imposing appearance would be perfect for the character they were creating. Ursula is only drawn with six tentacles, due to the studio's budget and difficulty in coordinating eight tentacles (though she has eight limbs if you include her arms). Pat Carroll has stated that this makes her a squid, though biologically she still resembles an octopus far more than any other sea-creature. Moreover, a squid has ten tentacles, not six. Her basic look was based on the Drag performer Divine, but Divine died before they could get his voice. The character has been compared to Madame Medusa from The Rescuers in terms of style, dramatics, and choice of minions.
